Ynet is the most popular general news site in Israel. On its main window there's
a news ticker - an iframe that displays scrolling news.
This ticker (I opened it's URL,
http://www.ynet.co.il/Ext/Comp/Ticker/Dhtml_Ticker/0,10016,L-184,00.html, in a
seperate window to isolate it) uses JavaScript, and takes about 80% of the CPU
on my machine (a 2.2Ghz mobile celeron) in Firefox, but only about 50% in IE. 
Its JS clearly does something wrong, but Firefox should not be worse than IE in
this.
As a workaround, I'm currently using Adblock to hide this iframe.

Reproducible: Always
